Tech Hammer

At the airport, Ning Wei was looking at his sister who was not far away and was explaining something to his sister, but her personality was far more showy and out-of-the-box than her sister. She was looking around. She couldn't help but sigh, and casually directed her words at the people around her. Asked: "Brother Liu, do you have any brothers or sisters?"

"Yes!" He replied concisely and concisely, which made Ning Wei feel a little short of breath.

One thing that struck him deeply was that since his status in his cognitive scope was getting higher and higher, there were more and more weird people around him, just like this person next to him who didn't seem to even know how to chat.

"How many are there? Brothers or sisters?" Ning Wei asked the same question in more detail. He turned and glanced at Liu Weiwei, and then realized that he, the nominal driver, seemed quite nervous. Although his head was The frequency of the swing is not high, but you can see that his eyes scanned almost everyone passing by the two of them. With the small Bluetooth headphones hanging on his ears, he really looked like a driver.

It's just that this vigilance is a bit exaggerated. As expected, there are fewer and fewer normal people around him.

Ning Wei sighed: "Brother Liu, this is China, and it's also an airport in the capital. You don't have to be so exaggerated, right?"

"Everyone has only one life, so you must be vigilant at all times. And there was something wrong with the coordination today. There are two groups of brothers who did not arrive at the designated observation point, so it is always right to be more cautious... Phew, okay Okay, everyone is in place." Liu Wei let out a long breath, and he looked really relaxed.

These words contained a huge amount of information, so much so that Ning Wei felt that he could brag to a few people in the dormitory group, and these uninformed people might not believe a word of it.

Really, Ning Wei really wanted to send a message in the group, and he had already thought of the copy: Now whenever Dad goes out to see someone off, a group of people will follow him. As for where these people are, even Dad himself doesn’t know...

"Well, I don't know much about this. For example, in today's airport environment, from your professional point of view, how many groups of people and how many points are needed to ensure absolute safety?" Ning Wei asked curiously. sentence.

"There are no absolutes. Different security measures are arranged according to different tasks and security levels. For example, for large-scale events, many brother units will cooperate, and the security plan is based on the situation. A complete set of plans are made, including various emergencies. All situations must be planned in advance. Different security levels must be divided according to different regions, which is a very complicated process." Liu Wei explained casually.

It still sounded very professional, but Ning Wei looked around and couldn't find any difference between the airport today and usual days. All I can see is the bustling crowd, orderly in the chaos...

"For example, today, the Ministry..., well, the company has arranged eight groups of brothers, and the security level is already very high."

"Huh...am I so important?" Ning Wei sighed.

Liu Wei glanced at Ning Wei with a complicated look, and said sincerely: "If you want to hear the truth, it can also be understood that you are more hateful. At least judging from some of the information we got, I don't want to see it. You have a lot of great people alive and kicking, and many of them are very capable.”

After saying that, Liu Wei seemed to be able to feel Ning Wei's unhappy mood, and added: "Speaking of which, I have been in the industry for a long time. You are the first person I have seen at this age who can offend the world with his ability. The future of young scientists with so many big names is bound to be limitless.”

Ning Wei regretted getting too familiar with Liu Wei. Really, when I chatted with Liu Wei before, this big brother didn't have this kind of talking style. It should be his style to chat to death about nothing, and he learned it in two days.

This further made him miss Yu Xingwei who locked himself in the supercomputing center to work on his graduation thesis. Speaking of it, Brother Yu's graduation thesis seemed to be finished soon. To be honest, Yu Xingwei was the best in terms of speaking ability. Chatting with him It always keeps people in a comfortable mood.

Fortunately, just when the conversation between the two reached an impasse, the student opposite Jiang had already raised his hand to help his sister straighten her collar. Based on Ning Wei's understanding of Classmate Jiang, this action showed that what needed to be explained was almost done. It was over, it was his turn to play, and Ning Wei also stepped forward with brisk steps.

"Brother-in-law, I'm leaving first. I'll leave my sister to you. You must have noticed that my sister is a standard good wife and mother. She may be nagging you, so you have to work hard. After I leave, you have to work hard. My sister is pregnant with little Ningning, so not only can I be my aunt next year, but my sister doesn’t have the energy to nag me anymore!”

Ning Wei, who had just walked up to the two girls and was still considering how to speak more appropriately to his status as brother-in-law, was shocked by his sister-in-law's sudden racing words. Really, it's hard to imagine that a sister-in-law who is a senior in high school can be so considerate. The only problem is probably that this statement is not very rigorous.

So as a rigorous scientific person, Ning Wei subconsciously corrected her: "No, if your sister can be pregnant with little Ningning after you leave, then you should be able to be an aunt by the end of this year, and you don't have to wait until next year!"

Student Jiang's little face instantly turned red due to the conversation between the two, and he naturally looked at Jiang Chenlu with a hint of murderous intent. However, before his reserved sister could react, Jiang Chenlu spoke again: "Look, Sister, let me just say that my brother-in-law had some idea in driving me back alone, right? Just test it out and you will find out the truth, so sister, you have to take care of yourself when I leave!"

This routine is a little deeper. Nowadays, the minds of high school students have become so complicated. Ning Wei feels that his character as a gentleman is about to be broken.

"Stop saying a few words and go back quickly. Remember what I told you!" Jiang said with a red face and glared at his sister.

"I know, sister, buy enough medicine for grandma at once, take it all away, and ask mom to video chat with you when you get home. At the New Year's Eve dinner, you will give red envelopes to mom and grandma. My second uncle likes to smoke Lotus King and is always reluctant to buy it. When you pay New Year greetings, you must bring two more, and there are still five thousand yuan that you need to return to your aunt privately. My uncle's side..."

"Jiang Chenlu..." Classmate Jiang called his sister's name in a suppressed voice. As soon as the full name was spoken, Feiyang's sister was immediately frightened, shrank her neck, and waved her hand at Ning Wei indiscriminately: "Brother-in-law, actually I I support you very firmly! I went to the security check first, let’s go!”

After saying that, she turned her head and walked towards the young lady waiting for her near the security checkpoint. Ning Wei was able to naturally and skillfully stretch out a hand to take the girl next to her into her arms in public. Mmm, soft and very fragrant!

Then he said confidently: "Ignore Chenlu, this little girl has learned bad things since coming to the capital! We want Xiao Ningning in the future not to upgrade her to aunt, but to do a long-lasting social experiment. "

As he said that, Ning Wei turned his head and saw the confused eyes of the girl next to him, and explained righteously: "My former roommate said that after a woman has a family and children, every time she scolds the children, she feels that she is too disrespectful. Reasonable, too tempered, not gentle enough. Next time, I need to correct myself and reason with my children. In the same situation, every time after scolding my husband, I will feel that what I just scolded was not harsh enough, and the meaning is not enough. I will try again next time. You must be more fierce when you scold! I just want to prove to them that you are definitely not like this! When you have children, whether they are children or husband, you will not scold!"

Well, regardless of whether Ning Wei really thinks so, it sounds very reasonable. Unfortunately, it is easier said than done. Although I have done enough psychological preparation, when there were only two people left in the whole room that night, Ning Wei still didn't have the nerve to rush into the river in the middle of the night after taking a shower. Classmate’s room…

This is definitely a very sad story. The sad result is that Ning Wei, who had always been in good physical condition after tossing and turning all night, had two dark circles under his eyes when he went out in the morning. He didn't have a good rest, so his mood was naturally not good. When he opened the door and faced Liu Wei, Ning Wei felt that the eyes of this old-fashioned guy who couldn't speak seemed to be full of ridicule.

It's so unreasonable that a single guy would mock him, a top student with a happy family? Well, maybe it was just his illusion, because Liu Wei just said hello to him and Jiang Chenshuang who was sending him out normally: "Good morning, Dr. Ning, classmate Jiang."

"Good morning, Brother Liu."

"Morning, Brother Liu, thank you for your hard work!"

Then classmate Jiang returned to the room, and the two of them silently went down the stairs and walked into the campus.

The campus is much cleaner after the holidays. There are no more energetic students on the way to the research center. Coupled with the gloomy weather in winter, it seems a bit lonely.

"Hey..." Ning Wei suddenly sighed, and Liu Wei glanced at him.

"I was a little tired last night, but I still have to deal with some things today. Sometimes I feel that our industry is really tiring." Ning Wei explained,

"It was very quiet last night? Didn't you rest? How could you be tired?" Liu Wei asked casually.

"A man and a woman are alone in the same room, and you can be as tired as you want. Brother Liu, you don't understand when you're single!" Ning Wei drove casually.

"Oh!" Liu Wei probably didn't want to continue this topic, so he responded, but he was probably stimulated by Ning Wei's last words. After all, he couldn't hold it back and said, "Nothing happened last night, how can you be tired?"

"Huh? How do you know we didn't do anything? Brother Liu, you have to speak responsibly!" Ning Wei asked unconvinced. Sure enough, this guy's eyes were mocking him when they met.

"This... probably because the TV sound lasted from ten to twelve yesterday." Liu Wei thought for a while and explained.

"Heh, Brother Liu, your judgment is very unreliable. Maybe the TV sound is because it masks other sounds?" Ning Wei asked unconvinced. He never suspected that surveillance or other eavesdropping equipment was installed in his house. With the existence of March, a BUG-level intelligent non-biological kitten on the Internet, it was unrealistic to transmit such information completely confidentially.

"Skills have specializations, and our profession is very accurate in judging people. In particular, we need to accurately control people's mental state and emotional judgment. For example, if someone passing by looks wrong, they will sense it. With Jiang Chenshuang's temperament , there really was a breakthrough relationship between you last night. When she saw me when she went out in the morning, her eyes would not be so calm, and her response to me would not be so natural." Liu Wei explained honestly.

When it came to extremely professional things, Ning Wei chose to shut up. It was as if he knew that if he talked about mathematics and physics formulas with Brother Liu next to him, he would definitely choose to shut up. They are all smart people, and everyone should not Will humiliate themselves on non-professional issues.

Fortunately, Ning Wei's phone rang at the right time, so Ning Wei didn't have to continue communicating with the guy who could read micro-expressions.

"Hey, Mr. Yan, do you have good news if you call so early?"

"Yes, Dr. Ning, good news. We have reached a preliminary agreement with Apple. If we cooperate with Cisco's authorization, our next-generation high-end models are expected to use 5G chips. Apple will temporarily provide us with 20 million A16 and 3000 chips in three batches. Ten thousand A15 chips. Of course, the price of these 50 million chips is not low, but it also solves our urgent need. With this buffer, it helps us gain at least two years, and it can also increase the number of Hongmeng users by one amount. class."

This news made Ning Wei stunned for a long time. This Huawei mobile phone is equipped with Apple's core CPU? What kind of magical negotiation idea is this? Mr. Yan is not afraid of increasing the workload of his engineers...

So Ning Wei was very confused and asked: "Well, Mr. Yan, wait a minute, if you want to use Apple's chips, doesn't it mean that your motherboard needs to be redesigned? And I remember that Apple's CPU has a relatively strong single-core processing capability. The multi-core capabilities are weak, which also means that in order to adapt to these CPUs, these two generations of products have specially launched special editions of Hongmeng systems?"

"These are small things. Half a year is enough to complete all the adaptations and adjust the entire set of adaptation software and hardware. And isn't there March? March is very powerful in terms of software optimization. In terms of matching, we With the brand new March smart voice system, we are very confident that we can win this turnaround! Of course, our self-developed Kirin CPU will not give up. With this confidence, we may be able to use the new smart platform in two years to talk about New story!”

Well, listening to Yan Ming's cheerful words, Ning Wei silently felt pity for the countless Huawei engineers who were destined not to have a long rest in the next six months for three seconds before asking: "So Apple is definitely willing to put its own data is interconnected with our platform?”

"This area is still being discussed, so I will call you to discuss it before negotiating. What Apple means is that it is impossible for them to communicate with each other in terms of commercial data. Laboratory test data can be communicated to a limited extent, but there are also many restrictions. For example, they can open some data to a limited extent, but this data can only be accessed and cannot be uploaded to the platform's server. This is a very tough apple to bite, so I want to hear your attitude?"

"Oh, whatever, it's fair, you get what you put in. In the future, it's enough that Apple needs to impose restrictions on data retrieval and use of some optimization functions on our platform. But I'm still curious, how does Apple Are you so easy to talk to? Are you willing to come up with 50 million CPUs? It's not easy for them, right?" Ning Wei asked slightly curiously.

"The A15 is definitely mainly in stock, and the A16 is also a generation behind Apple. The products they release next year will definitely be equipped with the A17 CPU. But these are not problems for us. Of course, they can be so straightforward, mainly I still want to get the car-building thing off the ground. After all, Apple’s car-building plan has been proposed for so many years, and so many people are looking at it eagerly, so being able to build a concept car now is of great significance to boost investor sentiment. !”

"In addition, in the field of mobile phones, although Apple definitely has technical redundancy accumulated over the years, after the launch of the intelligent voice control system in March, their technical upgrade redundancy will become embarrassing. So it is only beneficial to cooperate with us at this time. For them, 50 million CPUs is just one more order, and we also have to spend money to buy these chips."

These words are somewhat helpless. If you haven't had your neck really choked by someone, you can't experience how desperate that feeling of suffocation is. Ning Wei could probably understand Yan Ming's joy at surviving a desperate situation, but his mood was inexplicably depressed.

Ning Wei sighed: "Okay, you can just take care of the data exchange. I appreciate what you just said. It will definitely be a new story in two years. Hey, it is indeed Apple. It is really rich. Ming Knowing that it would be a loss-making business to build a concept car that would never be produced for the time being, they could launch it without even frowning. And the entire set of software for the new energy vehicle designed in March was written based on Hongmeng, right? If they want to switch to For the ISO version, the entire software needs to be rewritten, right? The cost is really high."

"Who says it's not? It's probably because Tesla has put a lot of pressure on Apple. But it doesn't matter, if Apple's concept car is actually produced, it can be regarded as advertising for our platform! And it's a good thing, Apple's car is really The one who is most anxious to build it should be Tesla, right?" Yan Ming said indifferently.

This makes sense, and I don't know what kind of sparks will be created when these two families collide. For a moment, Ning Wei felt a little bit excited.

"Okay, I'll build one later. I don't want a concept car. Whenever Apple releases their concept car, I'll take it out and show it to everyone." Ning Wei responded.

"Um..." The person on the other side was stunned. It is certainly feasible to build a car privately, but this does not consider mass production. The money invested can probably buy an airplane. However, thinking of Ning Wei's financial strength, Yan Ming naturally Knowing that Ning Wei really had the capital and willfulness, he immediately responded: "No problem, if you need our help, just let us know."

"Okay, thank you in advance! That's it, I'll hang up now."

After the call was made, the two of them almost reached the entrance of the research center. Ning Wei glanced at Liu Wei beside him and sighed: "You heard it, Brother Liu, I'm stuck. How is my laboratory application report?" ?Don’t delay, maybe it will be approved soon, and we can make universal chips suitable for civilian use."

The words were spoken a little too fast, making Liu Wei really want to pick this guy up and throw him into the Weiming Lake nearby to clear his mind. If he remembered correctly, this guy threw the information to him in a very clumsy way yesterday, and he started urging him today.

Not to mention that he glanced at it. If he really followed this guy's idea and just followed the first issue, it would cost tens of billions...

"I remember that the laboratory instruments at Yanbei University are all very advanced. They are not all useless, and they are one day earlier and one day later. Do you want to rub the chip out with your hands?" Liu Wei couldn't help but scolded.

"Rub your hands? I have something to say when it comes to this. Brother Liu, do you know what three-dimensional high-density through-silicon via array technology is? In layman's terms, it means making the chip higher. First, we have to make the through-silicon via array technology. tube, and then stuff specially structured carbon nanotubes into the silicon tube in a certain sequence, and then combine them to form a large integrated circuit, that is, a chip.”

"But do you know how many difficulties there are? First, we need to use two silicon plates to stagger the multi-walled carbon nanotube capacitor structure, and then use the inner and outer walls of the multi-walled carbon nanotubes to connect different electrodes to obtain greater coupling. Solve the problem of the limit of capacitive elements, but this method of structuring capacitors with inner and outer walls has extremely high process requirements and can hardly tolerate any industrial errors. Therefore, it is conceivable how high the scrap rate and cost will be. This requires consideration of other preparation methods. "

"Secondly, we must consider the impact of the size of the multi-walled carbon nanotube capacitor on performance, and the relationship between the resonant frequency of the capacitor and the material size and density. This requires repeated experiments to draw relatively reliable conclusions. Thirdly, heat dissipation In the process, the integrated circuit is in the silicon pass tube. In this three-dimensional mode, the density of the integrated circuit is extremely high, which requires the selection of materials with extremely high thermal conductivity to quickly export the accumulated heat. It is simple to say and does not require thousands of experiments. It can’t be solved at all.”

“The most important thing is that the process of preparing compliant nanotubes still requires repeated experiments, and then finding a low-cost preparation method that can be promoted. This requires us to study a series of methods that can prepare similar materials on a large scale in industry. Machinery, just like the electric arc furnace used in industry today to purify silicon oxide, requires cutting machines, rounding machines, and cutting machines after it is made into crystal ingots..."

"After completing this, we still need to explore a way, how to make these carbon nanotubes grow orderly in the silicon channel like our pre-designed circuit pattern. We must know that the chip manufactured by this process should theoretically reach Five to one billion carbon nanotubes. Of course, these are secondary. The important thing is that if some of the things that stay in the March intelligent simulation are successful, in theory we can find a new path."

"In other words, all the professional barriers set up by the entire chip industry are now ineffective. We don't have to rush to develop our own lithography technology, but directly use a new way to prepare future chips. As long as this chip shows With sufficient high performance, combined with China's huge internal market demand, we do not need to obtain the approval of others' standards. As long as we formulate internal standards, we can start large-scale applications in many areas."

"Of course the most important thing is that as long as we realize this technology, it doesn't even have to reach the point of mass production. For example, dozens of pieces are produced in the laboratory and directly supplied to Intel, TSMC, Samsung, and even Apple, Microsoft, etc. These companies mailed a few pieces to us and asked them to help us test them. I guarantee that the price of traditional silicon chips will soon enter a period of adjustment. Even after our equipment is built, people will come to discuss purchasing it as soon as possible."

"So is it wrong for me to be impatient? It's not that our laboratory equipment at Yanbei University is too far behind, but I want to do these experiments according to my heart. I need to make some adjustments to the equipment, but the equipment in the laboratory is all It’s from the school. So to be honest, I’m really embarrassed to do it. It’s not that I’m afraid of losing money if the training fails, but the key is that I’m afraid of delaying the project that my classmates are working on.”

"At least a month has passed for any set of imported instruments to go through the approval process. What if any of my seniors are unable to conduct experiments because they don't have the equipment, and end up delaying their graduation? Wouldn't I be hated to death? So, the laboratory still needs to be completed. My own talents are good. In short, there are many tasks, very arduous, and time is tight. Many people have placed great expectations on me. I must not live up to these expectations. Do you understand? "

Ning Wei glanced at Liu Weiyi, who was listening to a book from heaven. Well, the professionalism was overridden again, and he suddenly felt at ease! Although he is indeed not as good as Brother Liu when it comes to recognizing people by looking at them, at least he can understand the basic theory. But when it comes to what he has been studying recently, Ning Wei believes that Brother Liu is not only inferior to him, but he even doesn't understand it at all...

Sure enough, Liu Wei was silent at first, then silently walked to his door, turned around and said: "Uncle and aunt arrived at Jingxi Railway Station at 5:30 this afternoon. It has been arranged, we will leave on time at 4 pm , if classmate Jiang is going too, be sure to ask her to come on time."

"Oh! Okay, Brother Liu!" Ning Wei smiled and nodded at Liu Wei. He likes to deal with smart people. Everyone knows that they have to keep the pace in areas they are familiar with, so that they can be invincible.

…

What Ning Wei still doesn't know is that the information he submitted yesterday was indeed submitted to a certain big shot through special channels at the first time.

"This little guy, according to his ideas, can build more aircraft carriers!"

"In fact, we have carefully studied it and found that a lot of duplication of construction can be completely eliminated. As long as we coordinate well and let some brother research units cooperate well, it will save a lot of costs."

"Um……"

The boss pondered for a moment, and the money began to tick off Ning Wei's plan, and then said: "There is no need to save any money. Let's divide the entire project into five phases, and the first phase will be as he said , solve the problem starting from the point, and find an opportunity to tell that kid that if the points he proposed in the first period really achieve results, subsequent construction and equipment introduction will not be discounted! If there is no result, or the results are not up to expectations, haha... "

"Ok, I see!"
